Description

Die Erfindung bezieht sich auf eine Verladevorrichtung für Container od. dgl. mit einem Paar auf einem Fahrgestell aufbaubarer Ladeeinheiten, die jeweils eine um eine gemeinsame, in Längsmitte des Fahrgestells verlaufende Schwenkachse schwenkverstellbar an einer Konsole abgestützte Teleskopsäule aus einem an der Konsole angelenkten Unterteil, einem im Unterteil verschiebbar geführten Oberteil und einem den Oberteil gegenüber dem Unterteil schiebeverstellbaren Säulenzylinder aufweisen, wobei beidseits am Unterteil Stellzylinder angreifen und der Oberteil einen um eine zur Teleskopsäulenschwenkachse parallele Schwenkachse nach beiden Seiten schwenkverstellbaren Auslegerarm mit einem Widerlager zum Anschluß eines Lastaufnahmemittels aufnimmt.The invention relates to a loading device for containers or the like. With a A pair of loading units that can be mounted on a chassis, each one around a common, pivot axis running in the longitudinal center of the chassis supported on a console telescopic column from a hinged to the console Lower part, an upper part slidably guided in the lower part and one the upper part have adjustable column cylinders relative to the lower part, wherein engage the adjusting cylinder on both sides and the upper part one around the telescopic column swivel axis parallel swivel axis swiveling on both sides Cantilever arm with an abutment for connecting a load suspension device.

Eine solche Verladevorrichtung ist beispielsweise aus der EP 0 705 179 A bekannt und sie hat sich auch durchaus wegen ihres verhältnismäßig einfachen und kompakten Aufbaues, ihrer Robustheit und ihres im Vergleich zum Verladebereich geringen Platzbedarfes bewährt. Allerdings läßt sich bei der bekannten Verladevorrichtung der Auslegerarm der Teleskopsäulen nur lastfrei von einer Seite auf die andere umschwenken, so daß ein Ladevorgang, bei dem ein Container von einer Fahrgestellseite zur anderen bewegt werden soll, ein Abstellen des Containers auf dem Fahrgestell zum Entlasten und Umschwenken des Auslegerarms erfordert, was zeitraubend und umständlich ist. Außerdem kann der Auslegerarm unter Last nur in seiner anschlagbegrenzten Seitenschwenklage eingesetzt werden, womit eine gewisse Einschränkung der Lademöglichkeiten verbunden ist. Such a loading device is known for example from EP 0 705 179 A and it also has quite because of its relatively simple and compact structure, their robustness and their small footprint compared to the loading area proven. However, the cantilever arm can be in the known loading device swivel the telescopic columns from one side to the other only without load, see above that a loading process in which a container from one chassis side to another should be moved, parking the container on the chassis to relieve and swinging the boom arm requires what is time consuming and cumbersome. In addition, the cantilever arm can only be loaded in its side-pivot position that is limited by the load are used, with a certain restriction of the loading options connected is.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Verladevorrichtung der eingangs geschilderten Art zu schaffen, die ein Durchschwenken von Containem von der einen auf die andere Fahrgestellseite erlaubt und durch ein Schwenkverstellen der Auslegerarme auch unter Last eine Erweiterung des Verladebereiches und die Voraussetzung für ein Stapeln der Container mit sich bringt.The invention is therefore based on the object of a loading device at the beginning to create the kind described, which swings containers from one allowed on the other side of the chassis and by swiveling the extension arms an expansion of the loading area and the requirement even under load for stacking the containers.

Die Erfindung löst diese Aufgabe dadurch, daß der Oberteil der Teleskopsäule einen Säulenkopf trägt, der eine schlitzförmige Schwenkführung mit den Schwenkbereich beidseits begrenzenden Kurvenbahnen für den Auslegerarm bildet, daß der Auslegerarm den Kurvenbahnen zugeordnete Führungsglieder aufweist und mit einem Gleitstück gelenkig verbunden ist, das verschiebbar innerhalb des zur Schwenkführung des Säulenkopfes hin offen ausmündenden Oberteils sitzt, wobei im Mündungsbereich eine Engstelle zwischen den Kurvenbahnen zum gleichzeitigen Anliegen der Führungsglieder des in einer zur Teleskopsäule gestreckten Lage ausgerichteten Auslegerarms an beiden Kurvenbahnen vorgesehen ist, und daß der Säulenzylinder oberteilseitig am anschlagbegrenzt hochschiebbaren Gleitstück angreift.The invention solves this problem in that the upper part of the telescopic column Column head carries a slotted swivel guide with the swivel area curve paths for the cantilever arm which delimit on both sides form that the cantilever arm has the guide members assigned to the cam tracks and with a slider is articulated, which is slidable within the for pivoting the column head open-ended top sits, with a in the mouth area Narrowing between the cam tracks for simultaneous contact of the guide links of the outrigger arm aligned in a position extended to the telescopic column two cam tracks are provided, and that the column cylinder is limited on the upper side on the stop slidable attack attacks.

Die Stellzylinder können die Teleskopsäule in üblicher Weise um die gemeinsame, in Längsmitte des Fahrgestells verlaufende Schwenkachse nach beiden Seiten verschwenken, wobei unabhängig von der jeweiligen Schwenklage der Säulenzylinder innerhalb der Teleskopsäule nach beiden Richtungen betätigbar bleibt. Ist der Säulenzylinder in seine Ausgangsposition eingefahren, hat er einerseits den Oberteil in seine unterste Stellung gebracht und anderseits über das Gleitstück den Auslegerarm in den Oberteil eingezogen, wodurch der sich mit den Führungsgliedern entlang der Kurvenbahnen bewegende Auslegerarm fluchtend zur Teleskopsäule ausgerichtet ist. Beim Ausfahren des Säulenzylinders wird das Gleitstück hochgeschoben, womit der Auslegerarm entsprechend der Schwenklage der Teleskopsäule beim Hochfahren nach der einen oder anderen Seite hin entsprechend der die Führungsglieder führenden Kurvenbahn ausschwenkt und auf die betreffende Seite umklappt. Ist die Seitenschwenkgrenze durch das Anstehen des Gleitstückes am Endanschlag erreicht, wird bei weiterem Ausfahren des Säulenzylinders über das Gleitstück der Oberteil von seiner Grundposition heraus angehoben und läßt sich bis in eine gewünschte Ausfahrstellung gegenüber dem Unterteil hochschieben. Zusammen mit den Seitenschwenkmöglichkeiten der Teleskopsäule selbst ergeben sich so die unterschiedlichen Verlademöglichkeiten, wobei die Bewegungen der Teleskopsäule und auch des Auslegerarms auf Grund des entsprechend stark dimensionierten Säulenzylinders schwierigkeitslos auch unter Last erfolgen können. Damit bietet sich auch die einfache Möglichkeit, beispielsweise einen auf der einen Seite des Fahrgestells stehenden Container aufzunehmen, dann hochzuheben und auf die andere Fahrgestellseite zu schwenken und hier wieder abzusenken und abzustellen oder einen Container von der Ladefläche eines benachbarten Fahrzeuges auf die gegenüberliegende Fahrgestellseite zu bringen u. dgl..The actuating cylinders can move the telescopic column in the usual way around the joint Swivel the swivel axis running along the center of the chassis to both sides, regardless of the respective swivel position of the column cylinder within the telescopic column remains operable in both directions. Is the column cylinder retracted into its starting position, on the one hand it has the upper part in its brought to the lowest position and on the other hand the cantilever arm in the Upper part retracted, which means that the guide links along the curved tracks moving arm is aligned with the telescopic column. At the Extending the column cylinder, the slider is pushed up, with which the cantilever arm according to the swivel position of the telescopic column when starting up after one side or the other corresponding to the cam track guiding the guide members swings out and folds over to the relevant side. Is the side swing limit achieved by the fact that the slider is in contact with the end stop Extending the column cylinder over the slide of the upper part from its basic position lifted out and can be opposite to a desired extended position push up the lower part. Together with the side swivel options the telescopic column itself has different loading options, the movements of the telescopic column and also of the extension arm due to the correspondingly dimensioned column cylinders without difficulty even under load can be done. This also offers a simple option, for example one pick up containers standing on one side of the chassis, then lift them up and swivel to the other side of the chassis and lower again here and park or a container from the bed of an adjacent vehicle to bring to the opposite side of the chassis u. etc. ..

Damit der Auslegerarm einwandfrei mittels des Säulenzylinders schwenkverstellbar ist, muß der Oberteil der Teleskopsäule gegenüber dem Unterteil verschiebefest abgestützt sein, welche Abstützung von vornherein in eingezogener Teleskopposition gegeben ist. Um eine Schwenkverstellung des Auslegerarms auch in verschiedenen Ausfahrpositionen der Teleskopsäule vornehmen zu können, ist der Unterteil der Teleskopsäule mit einer Verriegelungsvorrichtung zum wahlweisen Verriegeln des Oberteils in ein oder mehreren Ausfahrstellungen ausgerüstet, so daß die Umschwenkhöhe des Auslegerarms und damit auch die Verladehöhe der Container wunschgemäß gewählt werden kann. Mit einer solchen vorbestimmbaren Arbeitshöhe der Teleskopsäule bzw. des Auslegerarms ist es nun auch möglich, Container so hoch anzuheben und seitlich zu verschwenken, daß ein Container auf eine entsprechend hohe Rampe, eine Ladefläche eines Fahrzeuges, aber auch zum Stapeln auf einen bereits abgestellten Container abgeladen bzw. von einem entsprechend hohen Abstellplatz aufgenommen werden kann.So that the cantilever arm can be easily pivoted using the column cylinder, the upper part of the telescopic column must be supported so that it cannot slide against the lower part be what support is given from the start in the retracted telescopic position. A swiveling adjustment of the extension arm also in different extension positions To be able to make the telescopic column, the lower part of the telescopic column is included a locking device for selectively locking the upper part in or equipped several extension positions so that the swing height of the boom arm and thus the loading height of the containers can be selected as desired can. With such a predeterminable working height of the telescopic column or the extension arm it is now also possible to lift containers so high and swivel them sideways, that a container on a correspondingly high ramp, a loading area a vehicle, but also for stacking on an already parked container or can be picked up from a correspondingly high parking space.

Als Führungsglieder für den Auslegerarm könnten geeignete Gleitflächen od. dgl. vorgesehen sein, doch besitzt zweckmäßigerweise der Auslegerarm als Führungsglied eine um eine zur Auslegerarmschwenkachse parallele Drehachse drehbar gelagerte Führungsrolle, die einen an die Engstelle zwischen den Kurvenbahnen angepaßten Durchmesser besitzt. Eine solche Führungsrolle erlaubt ein leichtgängiges, geräuscharmes Relativbewegen zwischen Auslegerarm und Säulenkopf und gewährleistet auch eine exakte Führung des Auslegerarmes beim Verschwenken wie beim fluchtenden Ausrichten im Engstellenbereich.Suitable sliding surfaces or the like could be provided as guide members for the cantilever arm be, but conveniently has the cantilever arm as a guide member a rotatably mounted about an axis of rotation parallel to the boom arm pivot axis Leading role, the one adapted to the narrow point between the cam tracks Has diameter. Such a guide roller allows a smooth, low-noise Relative movement between the boom arm and column head and also ensures precise guidance of the cantilever arm when swiveling as when in alignment Alignment in the narrow area.

Um zu verhindern, daß bei einem Verschwenken der Teleskopsäule während der Säulenzylinderbetätigung ein ungewolltes Umschlagen des Auslegerarms von einer Schwenkseite zur anderen erfolgt, was bei höherer Belastung zu einer Beschädigung der Verladevorrichtung führen könnte, ließe sich die Auslegerarmbewegung entlang einer entsprechenden Kulissenführung zwangsweise steuern, womit aber die Gefahr von Klemmungen u. dgl. verbunden wäre. Zweckmäßiger ist es daher, wenn der Auslegerarm mit einem einem Sperransatz des Säulenkopfes zugeordneten Sperriegel als Umschlagsicherung ausgestattet ist, welcher Sperriegel bei einem Hochschwenken des Auslegerarms vor dem Erreichen der Strecklage am Sperransatz anschlägt und eine Weiterbewegung verhindert. Erst wenn eine bewußte Entriegelung erfolgt, läßt sich die Sperre aufheben und das Umschwenken vornehmen.To prevent swiveling of the telescopic column during the Column cylinder actuation an unintentional turning of the cantilever arm from one Swiveling side to the other takes place, which leads to damage at higher loads could lead the loading device, the cantilever arm movement along forcibly control a corresponding scenery guide, but with it the danger of clamps and. Like. Would be connected. It is therefore more convenient if the extension arm with a locking bolt assigned to a locking projection of the column head as Envelope security is equipped, which locking bolt when swiveling the Cantilever arm strikes the locking shoulder before reaching the extended position and one Further movement prevented. Only when there is a deliberate release can the Remove the lock and swivel.

Ist nach einer weiteren Ausgestaltung der Erfindung die Teleskopsäule samt den Stellzylindern auf einem quer zur Schwenkachse schiebeverstellbaren Schlitten der Konsole aufgesetzt, kann durch diese Querverstellbarkeit der Verladebereich seitlich weiter ausgedehnt werden und es kommt zu einer Vergrößerung der Einsatzmöglichkeiten für die Verladevorrichtung.According to a further embodiment of the invention, the telescopic column together with the Actuating cylinders on a slide which is adjustable transversely to the swivel axis Mounted on the console, the loading area can be adjusted laterally due to this transverse adjustability be expanded further and there is an increase in the possible uses for the loading device.

Zweckmäßig ist es auch, wenn erfindungsgemäß die Konsole einen um eine liegende Querachse umklappbaren Oberbau aufweist, der die Teleskopsäule samt den Stellzylindern trägt, wodurch die üblicherweise über die Fahrerkabine hinausragenden Teile der Verladevorrichtung für einen Bahntransport od. dgl. im unbeladenen Zustand zur Verringerung der Transporthöhe umklappbar sind.It is also expedient if, according to the invention, the console is one lying around Transverse superstructure that can be folded over, which holds the telescopic column together with the actuating cylinders carries, whereby the parts that usually protrude beyond the driver's cab the loading device for a rail transport or the like in the unloaded state Reducing the transport height can be folded down.

Auf einem Fahrgestell 1, beispielsweise einem Lastkraftwagen, ist eine Verladevorrichtung für Container C mit zwei Ladeeinheiten 2 aufgebaut, wobei jede Ladeeinheit 2 aus einer Konsole 3, einer auf der Konsole 3 um eine in Längsmitte des Fahrgestells 1 verlaufende Schwenkachse I schwenkbar abgestützte Teleskopsäule 4 mit beidseits angreifenden Stellzylindern 5 sowie aus, der Übersichtlichkeit halber nur in Fig. 2 angedeuteten, nach beiden Seiten hin abschwenkbaren Stützfüßen 6 besteht. Wie in Fig. 1 dargestellt, kann die Konsole 3 zur Aufnahme der Teleskopsäule 4 und der Stellzylinder 5 einen quer zur Schwenkachse I schiebeverstellbaren Schlitten 7 aufweisen, um durch ein Seitenverstellen der Ladeeinheiten 2 den Verladebereich ausdehnen zu können. Außerdem ist es möglich, wie in Fig. 2 gezeigt, die Konsolen 3 mit einem um eine liegende Querachse II umklappbaren Oberbau 8 zur Aufnahme der Teleskopsäule 4 und der Stellzylinder 5 auszustatten, um zur Verringerung der Transporthöhe des unbeladenen Fahrzeuges die hochragenden Teile umzuklappen (strichlierte Darstellung). Dabei kann der Oberbau gegebenenfalls in nicht weiter dargestellter Weise zusätzlich zur Teleskopsäule auch die Stützfüße 6 aufnehmen, so daß die gesamten Ladeeinheiten umklappbar sind.On a chassis 1, for example a truck, there is a loading device for container C with two loading units 2, each loading unit 2 from a console 3, one on the console 3 by one in the longitudinal center of the chassis 1 extending pivot axis I pivotally supported telescopic column 4 with on both sides attacking actuating cylinders 5 and, for the sake of clarity, only indicated in FIG. 2, support feet 6 which can be swiveled towards both sides. As in Fig. 1 shown, the console 3 for receiving the telescopic column 4 and the actuating cylinder 5 have a slide 7 which is adjustable transversely to the pivot axis I in order to pass through a lateral adjustment of the loading units 2 to be able to expand the loading area. It is also possible, as shown in Fig. 2, the consoles 3 by one horizontal transverse axis II foldable superstructure 8 for receiving the telescopic column 4 and the actuating cylinder 5 in order to reduce the transport height of the unloaded Vehicle to fold up the towering parts (dashed line). The superstructure can, if necessary, additionally in a manner not shown to the telescopic column also take the support feet 6 so that the entire loading units are foldable.

Die Teleskopsäule 4 besteht, wie insbesondere aus Fig. 3 hervorgeht, aus einem auf der Konsole 3 angelenkten Unterteil 9, an dem über geeignete Anschlußplatten 10 die Stellzylinder 5 angreifen, aus einem im Unterteil 9 verschiebbar geführten Oberteil 11, der am freien Ende einen Säulenkopf 12 trägt, einem innerhalb des Oberteils 11 verschiebbar eingesetzten Gleitstück 13, an dem um eine zur Schwenkachse I parallele Schwenkachse III schwenkverstellbar eine Auslegerarm 14 mit einem Widerlager 15 zum Anschluß eines Lastaufnahmemittels 16, beispielsweise eines Traggeschirrs zur Aufnahme eines Containers, angelenkt ist, sowie aus einem Säulenzylinder 17, der sich einerseits am Unterteil 9 bzw. an der Schwenkachse I abstützt und der anderseits am Gleitstück 13 angreift, das bis zu einem nicht weiter dargestellten Endanschlag aus dem Oberteil 11 bis in den Säulenkopf 12 hochschiebbar ist. Der Säulenkopf 12 bildet eine schlitzförmige Schwenkführung 18 für den Auslegerarm 14, wobei der Schwenkbereich durch seitliche Kurvenbahnen 19 begrenzt wird. Der Auslegerarm 14 ist mit den Kurvenbahnen 19 zugeordneten Führungsgliedem, beispielsweise mit um eine zur Anlenkachse III parallele Drehachse IV drehbaren Führungsrollen 20 ausgerüstet, welche Führungsrollen 20 im Durchmesser an die im Mündungsbereich des Oberteils 11 zur Schwenkführung 18 des Säulenkopfes 12 hin vorgesehene Engstelle 21 zwischen den beiden Kurvenbahnen 19 angepaßt sind, so daß sich bei einem Einwärtsziehen des Gleitstückes 13 der Auslegerarm 14 in eine zur Teleskopsäule 4 gestreckte Lage ausrichten läßt.The telescopic column 4, as can be seen in particular from FIG. 3, consists of one the console 3 articulated lower part 9, on which the suitable connecting plates 10 Actuate the actuating cylinder 5, from an upper part 11 which is displaceably guided in the lower part 9, which carries a column head 12 at the free end, one displaceable within the upper part 11 used slider 13, on the one parallel to the pivot axis I Swivel axis III is a cantilever arm 14 with an abutment 15 for connecting a load-carrying device 16, for example a supporting harness for Inclusion of a container, which is articulated, and from a column cylinder 17, which is on the one hand on the lower part 9 or on the pivot axis I and on the other hand on Slider 13 attacks that up to an end stop, not shown the upper part 11 can be pushed up into the column head 12. The column head 12 forms a slot-shaped swivel guide 18 for the cantilever arm 14, the swivel range is limited by lateral cam tracks 19. The cantilever arm 14 is with the Guide tracks associated with cam tracks 19, for example with one about the articulation axis III parallel axis of rotation IV equipped rotatable guide rollers 20 which Guide rollers 20 in diameter to those in the mouth region of the upper part 11 Swivel guide 18 of the column head 12 provided constriction 21 between the two cam tracks 19 are adapted so that when pulling the Align the slider 13 of the cantilever arm 14 in a position extended to the telescopic column 4 leaves.

Der Säulenkopf 12 bildet einen mittigen Sperransatz 22, dem ein Sperriegel 23 des Auslegerarms 14 als Umschlagsicherung zugehört, wobei der Sperriegel 23 beispielsweise als doppelt beaufschlagbarer Sperrzylinder 24 zum wahlweisen Ver- und Entriegeln ausgebildet ist.The column head 12 forms a central locking projection 22 to which a locking bolt 23 of the Cantilever arm 14 is listened to as a cover, the locking bolt 23 for example as a double acting lock cylinder 24 for optional locking and unlocking is trained.

Am Unterteil 9 der Teleskopsäule 4 ist eine Verriegelungsvorrichtung 25 angeordnet, die aus zwei voneinander in Säulenlängsrichtung beabstandeten Riegelkämmen 26, 27 und einem über Schwenkhebel 28 an den beiden Verriegelungskämmen angelenkten Betätigungszylinder 29 besteht, so daß durch die Betätigung des Betätigungszylinders 29 beide Verriegelungskämme 26, 27 ausgerückt oder abwechselnd der eine oder andere in seine Verriegelungsstellung eingerückt werden können. In den Verriegelungsstellungen ragen die Riegelkämme durch entsprechende Öffnungen in den Unterteil 9 hinein und untergreifen den Oberteil 11 in einer mittleren bzw. oberen Ausfahrstellung, wobei durch einen Formschluß zwischen den Riegelkämmen und dem Oberteil oder eine entsprechend schwache Dimensionierung des Betätigungszylinders 29 ein Entriegeln bei belastetem Oberteil nicht möglich ist.A locking device 25 is arranged on the lower part 9 of the telescopic column 4, the bar combs 26, 27 spaced apart from one another in the longitudinal direction of the column and one articulated via pivot lever 28 on the two locking combs Actuating cylinder 29, so that by actuating the actuating cylinder 29 both locking combs 26, 27 disengaged or alternately one or the other can be engaged in its locking position. In the locking positions the bar combs protrude through corresponding openings in the lower part 9 and reach under the upper part 11 in a middle or upper extension position, whereby by a positive connection between the bolt combs and the upper part or a correspondingly weak dimensioning of the actuating cylinder 29 unlocking is not possible when the upper part is loaded.

Die erfindungsgemäßen Ladeeinheiten 2 erlauben nicht nur ein Aus- und Einfahren bzw. ein Verschwenken der Teleskopsäule 4, sondern auch ein Schwenkverstellen des Auslegerarms 14 und auch ein Umschwenken dieses Auslegerarms 14 unter Last, so daß sich ein breiter Einsatzbereich mit den unterschiedlichsten Verlademöglichkeiten ergibt. So läßt sich beispielsweise, wie in Fig. 1 angedeutet, ein Container C von einer erhöhten Ladefläche L abnehmen oder auf eine solche erhöhte Ladefläche L abstellen, es ist ein Umladen des Containers C von einer Fahrzeugseite auf die andere und ein Abstellen am Boden, aber auch ein Aufeinanderstapeln zweier Container C möglich. Darüber hinaus lassen sich die Ladeeinheiten 2 in eine Transportstellung bringen, die, wie ebenfalls in Fig. 1 angedeutet, innerhalb der Außenkontur eines aufgeladenen Containers C Platz findet. The loading units 2 according to the invention not only allow an extension and retraction or a pivoting of the telescopic column 4, but also a pivoting adjustment of the Cantilever arm 14 and also a pivoting of this cantilever arm 14 under load, so that there is a wide range of applications with a wide variety of loading options results. For example, as indicated in FIG. 1, a container C of one remove the raised loading area L or place it on such an increased loading area L, it is a reloading of the container C from one side of the vehicle to the other and one Parking on the ground, but also stacking two containers C possible. In addition, the loading units 2 can be brought into a transport position which, as also indicated in Fig. 1, within the outer contour of a loaded container C finds place.

Die Seitenschwenkbewegungen der Teleskopsäule 4 werden über die Stellzylinder 5 vorgenommen, wobei unabhängig von den Schwenklagen der innere Säulenzylinder 17 zum Schwenkverstellen des Auslegerarms 14 oder zum Aus- und Einfahren des Oberteils 11 betätigt werden kann. Wird beispielsweise der Säulenzylinder 17 in der in Fig. 3 dargestellten Lage, die einer ersten Ausfahrstellung des Oberteils mit einer Verriegelung durch den unteren Verriegelungskamm 26 entspricht, im Ausfahrsinn beaufschlagt, wird das Gleitstück 13 hochbewegt und damit der Auslegerarm 14 unter Abrollen der Führungsrollen 20 entlang der Kurvenbahn 19 seitlich ausgeschwenkt, wobei durch ein seitliches Schwenkverstellen der Teleskopsäule 4 die Auslageweite vergrößert werden kann. Wird der Säulenzylinder 17 eingefahren, erfolgt auf Grund der Verriegelung des Oberteils 11 ein Hochschwenken des Auslegerarms 14 in Richtung Strecklage, bis der Sperriegel 23 am Sperransatz 22 anliegt, was ein ungewolltes Umschlagen des Auslegerarms 14 verhindert. Werden die Sperriegel 23 entriegelt, kann durch ein weiteres Rückziehen des Säulenzylinders 17 das Gleitstück 13 bis zur Strecklage des Auslegerarms 14 in den Oberteil 11 eingezogen werden, wobei die Führungsrollen 20 im Bereich der Engstelle 21 nun gleichzeitig an beiden Kurvenbahnen 19 anliegen und die Mittellage des Auslegerarms 14 stabilisieren. Ist während dieses Einholvorganges oder nach dem Erreichen der Strecklage die Teleskopsäule 4 von der einen Seite auf die andere übergeschwenkt, kann nun bei einem Hochschieben des Gleitstückes 13 mittels des Säulenzylinders 17 der Auslegerarm 14 mit seinen Führungsrollen 20 entlang der anderen Führungsbahn 19 auf die andere Seite umschwenken und die aufgenommene Last bei seiner Schwenkbewegung mitnehmen. Ist der Umschwenkvorgang beendet und hat beim Ausfahren des Säulenzylinders 17 das Gleitstück 13 seinen Endanschlag erreicht, wird bei weiterer Beaufschlagung des Säulenzylinders 17 zusammen mit dem Gleitstück 13 der Oberteil 11 ausgefahren, was zu einer Erhöhung der Teleskopsäule 4 führt. Sobald der Oberteil die Verriegelungsvorrichtung 25 entlastet, läßt sich der Verriegelungskamm 26 herausziehen und gegebenenfalls nach einem entsprechenden Ausfahren des Oberteils 11 der höherliegende Verriegelungskamm 27 einsetzen, so daß nun in einer weiteren Ausfahrstellung, beispielsweise in einer Stapelposition, durch ein Zurückziehen des Säulenzylinders 17 wiederum der Auslegerarm 14 schwenkverstellt werden kann.The lateral pivoting movements of the telescopic column 4 are via the actuating cylinder 5 made, regardless of the pivot positions of the inner column cylinder 17th for swiveling the extension arm 14 or for extending and retracting the upper part 11 can be operated. For example, if the column cylinder 17 in FIG. 3 shown position, the first extended position of the upper part with a lock corresponds to the lower locking comb 26, acted upon in the direction of extension, the slider 13 is moved up and thus the cantilever arm 14 while the Guide rollers 20 swung out laterally along the cam track 19, with a lateral pivot adjustment of the telescopic column 4, the display width can be increased can. If the column cylinder 17 is retracted, due to the locking of the Upper part 11 a pivoting of the cantilever arm 14 in the extended position until the Locking bolt 23 bears against the locking projection 22, which results in an unintentional turning over of the cantilever arm 14 prevented. If the locking bolt 23 is unlocked, another can Retracting the column cylinder 17, the slider 13 to the extended position of the cantilever arm 14 are drawn into the upper part 11, the guide rollers 20 in the area the constriction 21 now abut simultaneously on both curved tracks 19 and the Stabilize the middle position of the extension arm 14. Is during this catching up or after reaching the stretched position, the telescopic column 4 from one side to the other pivoted, can now by pushing the slide 13 by means of of the column cylinder 17 of the cantilever arm 14 with its guide rollers 20 along the swivel another guideway 19 to the other side and the recorded one Take the load with you when swinging. The swivel process is finished and when the column cylinder 17 extends, the slide 13 has its end stop reached, is further applied to the column cylinder 17 together with the Slider 13 of the upper part 11 extended, which leads to an increase in the telescopic column 4 leads. As soon as the upper part relieves the locking device 25, the locking comb can be released 26 pull out and if necessary after a corresponding one Extend the upper part 11 of the higher-level locking comb 27, see above that now in a further extended position, for example in a stacking position a retraction of the column cylinder 17 in turn the cantilever arm 14 pivotally adjusted can be.
